Because there is an absolute value in this equation around the x and and you are only adding something to that, we know that this will always be positive. This eliminates all the choices except for [1,infinity), the third option.

Find the volume of the ellipsoid x2+y2+4z2=100x2+y2+4z2=100.

kondor19780726 [428]

Given the ellipsoid $x^2+y^2+4z^2=100$

For the radius in the x-dirextion, y = z = 0, and we have

$x^2=100 \\ \\ \Rightarrow x=\pm10$

For the radius in the y-dirextion, x = z = 0, and we have

$y^2=100 \\ \\ \Rightarrow y=\pm10$

For the radius in the z-dirextion, x = y = 0, and we have

$4z^2=100 \\ \\ \Rightarrow z^2=25 \\ \\ \Rightarrow z=\pm5$

Thus, the radius of the ellipsoid is given by

$Volume=4\pi r^3=4\pi\times10\times10\times5=500\pi$

Item 5 The frequency of the musical note F4 is about 349.23 Hz. What is the frequency of the note one octave above F4? 698.46 Hz

ira [324]

Answer:

698.46 Hz

Step-by-step explanation:

A note an octave higher than another note is double the amount of frequency.

In this example, the note is 349.23 Hz. Doubled, this is 698.46 Hz. Therefore, the final answer is the first option, 698.46 Hz

How do you know when ratios are equivalent and when they are not equivalent

White raven [17]

Ratios are equivalent when that can be reduced or multiplied to be the same number.
Ex) 1:4 is the same as 2:8 or 4:16
10:20 is the same as 8:16 or 1:2

They are not equivalent if you can’t do this

pychu [463]

Answer:

187

Step-by-step explanation:

a=12,d=17-12=5

nth term =a+(n-1)d

36th term=12+(36-1)5

=12+(35×5)

12+175

36th term=187
